-the game ends at the fourth toss
I will try to explain it as simple as possible.
Game ends in 4rth toss, implies that first three are failures. so there are 4 events, Three Tails and One head, and all are
independent events.........So Probabiltiy is 0.5*0.5*0.5*0.5 = 0.0625
-the first player wins the game.
Applying the same logic.
0.5 is the answer
-the second player wins the game.
Again same Logic
Answer is 0.25
